/* ============================================================
   Installation & Technical Support page — section layout
   Continues the Support pages' grammar (Warranty, Delivery):
   alternating white / light-grey sections, a copy-photo split,
   fact cards with a green left edge, check rows, responsibility
   cards and blue numbered stages. Colours and type come from
   tokens.css; .eyebrow, .section-heading and .text-link are
   global (site.css). Local prefix: nz-inst-.

     column's height, and the picture crops inside it (object-fit: cover).
     A height:0 + min-height:100% grid item cannot do this: during track
     sizing the percentage falls back to auto and the slot's intrinsic
